Globals Used

API ID: CountGlobalsUsed
Languages: C, C++, Pascal, Python, Web
Targets: Functions

The number of times this function uses global objects

Example:

    int my_global = 10;
    void uses(int x)
    {
      int y, z;
      x = 1;           //     Parameters do not count
      x = 2;           //     Parameters do not count
      y = 1;           //     Locals do not count
      y = 2;           //     Locals do not count
      my_global = 1;   // + 1 Globals count
      my_global = 2;   // + 1 Duplicates count
    }                  // CountGlobalsUsed = 2
